Abstract
Description
La présente invention concerne un engin volant du type ultra-léger motorisé, comportant une nacelle avec poste de pilotage, une voilure de sustentation, des moyens de propulsion destinés à souffler de l'air vers l'arrière dudit engin et des moyens de pilotage.The present invention relates to a flying machine of the ultra-light motorized type, comprising a nacelle with a cockpit, a lift wing, propulsion means intended to blow air towards the rear of said machine and control means.
Ce type d'engin volant autonome est connu depuis plusieurs années. En général la voilure de sustentation se présente souvent sous la forme d'une aile dite "delta", et elle est constituée d'une armature rigide recouverte d'une toile. La voilure est le plus souvent démontable, de manière à permettre un transport aisé de l'engin sous un faible volume.This type of autonomous flying machine has been known for several years. In general, the airfoil is often in the form of a so-called "delta" wing, and it consists of a rigid frame covered with a canvas. The wing is most often removable, so as to allow easy transport of the machine in a small volume.
On connaît également, dans les milieux sportifs, l'utilisation de parachutes de type "aile" qui ont l'avantage d'obéir aux mêmes principes aérodynamiques qu'une aile de planeur. Toutefois, l'utilisation de ce type de parachute à partir du sol nécessite un départ à partir d'un point de lancement situé en altitude et un déploiement préalable du parachute que le parachutiste, qui en est équipé, obtient en courant au point ce lancement avant de s'élancer dans le vide.We also know, in sports circles, the use of "wing" type parachutes which have the advantage of obeying the same aerodynamic principles as a glider wing. However, the use of this type of parachute from the ground requires a departure from a launch point located at altitude and a prior deployment of the parachute that the parachutist, who is equipped with it, obtains by running at this launch point. before rushing into the void.
On connaît également l'utilisation d'un parachute de type "aile" en tant que parachute ascensionnel. Dans ce cas, le parachutiste est tracté par des moyens appropriés qui se déplacent sur le sol.We also know the use of a "wing" type parachute as a parasail. In this case, the paratrooper is towed by appropriate means which move on the ground.
L'état de la technique le plus proche de la présente invention est illustré par la demande de brevet européen EP-A-0 130 925. Ce document dévoile en effet un engin volant de type ultra-léger motorisé, comportant une nacelle avec poste de pilotage une voilure de sustentation, des moyens de propulsion destinés à souffler de l'air vers l'arrière dudit engin et des moyens de pilotage, la voilure de sustentation étant constituée d'un parachute de type "aile", aux suspentes duquel ladite nacelle est accrochée. Le glonfement de la voilure et son positionnement au-dessus de la nacelle résultant de la vitesse acquise par l'engin dans la phase de décollage, ce qui nécessite une longueur de décollage relativement grande.The state of the art closest to the present invention is illustrated by European patent application EP-A-0 130 925. This document indeed discloses a motorized ultra-light type flying machine, comprising a nacelle with a position of piloting a lift wing, propulsion means intended to blow air towards the rear of said machine and piloting means, the lift wing consisting of a "wing" type parachute, to the lines of which said nacelle is hung. The swelling of the wing and its positioning above the nacelle resulting from the speed acquired by the craft in the takeoff phase, which requires a relatively long takeoff length.
US-A-3 443 779 concerne une aile flexible munie de raidisseurs gonflables et d'une manche à air susceptible de capter une partie de l'air propulsé vers l'arrière par les moyens de propulsion de manière à gonfler les raidisseurs. Ce document ne fournit aucun enseignement sur les moyens pour déployer et positionner l'aile au-dessus d'une nacelle lors de la phase de décollage.US-A-3,443,779 relates to a flexible wing provided with inflatable stiffeners and an air bag capable of capturing part of the air propelled rearward by the propulsion means so as to inflate the stiffeners. This document does not provide any teaching on the means for deploying and positioning the wing over a nacelle during the takeoff phase.
Le but de l'invention est de réaliser un engin volant du type mentionné ci-dessus qui utilise une voilure souple du type parachute et qui puisse décoller sur une très courte distance.The object of the invention is to produce a flying machine of the type mentioned above which uses a flexible wing of the parachute type and which can take off over a very short distance.
L'invention atteint son but par le fait que ledit engin volant comporte, de plus, des moyens pour dévier, à la demande, au moins une partie de l'air soufflé par lesdits moyens de propulsion de manière à permettre, dans la phase précédant le décollage dudit engin, le gonflement de ladite voilure, son déploiement et son positionnement au-dessus de ladite nacelle, lesdits moyens pour dévier au moins une partie de l'air soufflé par les moyens de propulsion étant portés par ladite nacelle.The invention achieves its object by the fact that said flying machine further comprises means for deflecting, on demand, at least part of the air blown by said propulsion means so as to allow, in the preceding phase the takeoff of said machine, the inflation of said airfoil, its deployment and its positioning above said nacelle, said means for deflecting at least part of the air blown by the propulsion means being carried by said nacelle.
Grâce à cette conception de l'engin, celui-ci peut décoller par ses propres moyens en roulant sur une faible longeur, après déploiement de la voilure.Thanks to this design of the craft, it can take off on its own by rolling over a short length, after deployment of the airfoil.
Il est à noter que, lorsque l'engin est à l'arrêt sur le sol, le volume d'air nécessaire pour déployer la voilure est relativement faible, et ce volume d'air est fourni par les moyens de propulsion tournant au ralenti.It should be noted that, when the machine is stopped on the ground, the volume of air necessary to deploy the wing is relatively small, and this volume of air is supplied by the propulsion means running at idle.
L'orientation du flux d'air dans la direction verticale de bas en haut sur la voilure permet un vol presque stationnaire.The orientation of the air flow in the vertical direction from bottom to top on the wing allows an almost hovering flight.
Lorsque le parachute est gonflé et positionné au-dessus de la nacelle, le flux d'air est de nouveau dirigé vers l'arrière de l'engin assurant alors le déplacement horizontal de l'engin sur le sol et son décollage, le parachute fonctionnant maintenant comme un parachute ascensionnel.When the parachute is inflated and positioned above the nacelle, the air flow is again directed towards the rear of the craft then ensuring the horizontal displacement of the craft on the ground and its takeoff, the parachute functioning now like a parasail.
Les moyens de propulsion de l'engin comportent au moins une hélice de propulsion actionnée par un moteur.The means of propulsion of the machine comprise at least one propeller propeller actuated by a motor.
De préférence, les moyens pour dévier au moins une partie de l'air soufflé par lesdits moyens de propulsion comportent un arbre horizontal pivotable disposé transversalement sur ladite nacelle et dont le pivotement est commandé, dudit poste de pilotage, par des moyens de commande, et l'une au moins des hélices des moyens de propulsion est portée par ledit arbre.Preferably, the means for deflecting at least part of the air blown by said propulsion means comprise a pivotable horizontal shaft disposed transversely on said nacelle and the pivoting of which is controlled, from said cockpit, by control means, and at least one of the propellers of the propulsion means is carried by said shaft.
Avantageusement, une extrémité au moins dudit arbre est munie d'un plan mobile disposé à l'extérieur de la nacelle et une hélice est montée sur ledit plan mobile.Advantageously, at least one end of said shaft is provided with a movable plane disposed outside the nacelle and a propeller is mounted on said movable plane.
Grâce à cette structure, au moins une hélice de propulsion de l'engin est orientable à la demande du pilote. Ceci lui permet de diriger le souffle d'air produit par cette hélice vers la voilure, lors de la phase préparatoire au décollage, pour gonfler celle-ci et la positionner au-dessus de la nacelle.Thanks to this structure, at least one propulsion propeller of the machine is adjustable at the request of the pilot. This allows it to direct the breath of air produced by this propeller towards the airfoil, during the preparatory phase for takeoff, to inflate it and position it above the nacelle.
Pour permettre une orientation correcte du souffle d'air, l'arbre peut pivoter par rapport à la nacelle d'un quart de tour environ.To allow correct orientation of the air blast, the shaft can pivot relative to the nacelle by about a quarter of a turn.
Avantageusement, l'arbre est solidaire de deux plans mobiles disposés de part et d'autre de la nacelle, et les moyens de propulsion comportent au moins deux hélices montées respectivement sur lesdits plans mobiles.Advantageously, the shaft is integral with two movable planes arranged on either side of the nacelle, and the propulsion means comprise at least two propellers mounted respectively on said movable planes.

Le dessin montre on engin volant 1 conforme à l'invention.The drawing shows a
Cet engin 1 comporte essentiellement une nacelle 2 fixée aux suspentes 3 d'un parachute 4, du type "aile" qui constitue la voilure de sustentation de l'engin 1.This
La voilure est fixée à la nacelle 2 par quatre points d'ancrage répartis d'une façon quadrangulaire de manière à annuler l'effet balançoire.The airfoil is fixed to the
La nacelle 2 peut reposer sur le sol 5 au moyen de roues 6 prévues aux extrémités inférieures ce jambes de support 9 s'étendant sous la nacelle 2. Elle est réalisée dans des matériaux légers, du plastique par exemple, et elle comporte un poste de pilotage 10 pouvant recevoir le pilote et éventuellement ces passagers.The
L'engin comporte en plus des moyens de pilotage et des moyens de propulsion 11 destinés à souffler de l'air vers l'arrière de la nacelle 2.The machine also comprises piloting means and propulsion means 11 intended to blow air towards the rear of the
Ces moyens de propulsion 11 sont constitués par au moins une hélice 12 disposée de préférence dans un carénage 13 de forme tubulaire. L'hélice 12 est entraînée par un moteur non représenté. sur le dessin.These propulsion means 11 are constituted by at least one
Selon l'invention, au moins une partie de l'air soufflé par les moyens de propulsion 11 peut être déviée sans discontinuité, à partir de sa trajectoire normale, dirigée à l'horizontale, vers une trajectoire verticale dirigée au-dessus de la nacelle 2, à la demande du pilote, de manière à permettre, lors de la phase préparatoire avant décollage de l'engin 1, le gonflement et le déploiement de la voiture 4 ainsi que son positionnement au-dessus de la nacelle 2.According to the invention, at least part of the air blown by the propulsion means 11 can be deviated without discontinuity, from its normal trajectory, directed horizontally, towards a vertical trajectory directed above the
Lorsque la voilure 4 se trouve au-dessus de la nacelle 2 dans la position normale de sustentation, le souffle d'air est de nouveau dirigé vers l'arrière de la nacelle par action du pilote sur un organe de commande approprié, les freins de blocage des roues 6 sont ensuite lâchés, et la voilure 4 agit alors comme un parachute ascensionnel qui provoque le décollage de la nacelle 2 sur une très courte distance.When the
Selon un mode de réalisation préféré de l'invention, les moyens de propulsion 11 sont fixés sur un plan mobile 14 disposé à l'extérieur de la nacelle 2. Ce plan mobile 14 est lui-même solidaire d'un arbre horizontal pivotable 15 qui est monté transversalement sur la nacelle 2. Cet arbre 15 peut pivoter d'un quart de tour et il est commandé à partir du poste de pilotage 10 par des moyens de commande appropriés. De préférence l'arbre 15 traverse la nacelle 2 de part en part, et il est prévu un plan mobile 14 à chacune de ses extrémités. Les carénages 13 sont fixés aux plans mobiles 14. Les moyens de propulsion 11 comportent dans ce cas deux hélices de propulsion 12 qui sont entraînées soit par des moteurs individuels disposés à l'intérieur des carénages 13, soit par un moteur unique monté sur la nacelle 2 ou solidaire ce l'arbre 15 et pivotable avec celui-ci.According to a preferred embodiment of the invention, the propulsion means 11 are fixed on a
Les figures 2 à 4 montrent diverses vues de l'engin lors de la phase préparatoire au décollage.Figures 2 to 4 show various views of the aircraft during the preparatory phase for takeoff.
Sur la figure 2 on voit la nacelle 2 à l'arrêt sur le sol. La voilure 4 est disposée à l'arrière ce la nacelle 2 et les carénages 13 sont dirigés vers l'arrière. Lorsque l'on fait fonctionner les hélices 12, le souffle d'air 16 fait gonfler la voilure 4. Comme on le voit sur la figure 3, le pivotement ce l'arbre 15, entraîne le pivotement du souffle d'air 16 qui entraîne à son tour une remontée de la voilure 4 disposée au-dessus de la nacelle 2, le souffle d'air 16 étant alors dirigé vers le haut. Le pilote lâche alors les freins de blocage des roues 6, puis il fait pivoter l'arbre 14 afin que le souffle d'air 16 soit de nouveau dirigé vers l'arrière provoquant alors le déplacement de la nacelle 2 sur le sol 5. La voilure 4 agit alors comme un parachute ascensionnel et l'engin 1 quitte le sol 5.In Figure 2 we see the
Diverses modifications peuvent être apportées par l'homme de métier à l'engin volant 1 décrit ci-dessus. En particulier, les roues 6 peuvent être remplacées par des skis ou des flotteurs pour permettre le décollage ou l'atterrissage de l'engin à partir de champs de neige ou de plans d'eau.Various modifications can be made by a person skilled in the art to the
Lorsque l'engin est équipé de plusieurs moteurs de propulsion, on peut prévoir que seuls quelques-uns d'entre eux soient orientables.When the machine is equipped with several propulsion motors, provision may be made for only a few of them to be steerable.
On comprend aisément que l'engin volant décrit ci-dessus permette la pratique ce l'aéronautisme sans danger, car en cas de panne des moteurs de propulsion, la voilure de sustentation fonctionne comme un parachute de type "aile".It is easy to understand that the flying machine described above allows aeronautics to be practiced without danger, because in the event of failure of the propulsion engines, the airfoil operates like a "wing" type parachute.
Il est à noter que l'orientation du flux d'air dans la direction verticale de bas en haut sur la voilure permet un vol presque stationnaire.It should be noted that the orientation of the air flow in the vertical direction from bottom to top on the wing allows an almost stationary flight.
La figure 6 montre l'engin volant 1 dans une phase de vol presque stationnaire qui est assurée en altitude, en faisant tourner les moteurs d'entraînement au ralenti maximum et en dirigeant le léger souffle des hélices 12 vers la voilure 4. Cette phase ce vol nécessite bien entendu une fonction de pilotage appropriée.FIG. 6 shows the flying
Il est bien évident que ce positionnement de l'ensemble n'assure pas un vol stationnaire idéal, mais couplé avec un léger vent de face, il peut apporter une aide particulière inconnue à ce jour sur ces catégories d'appareils.It is obvious that this positioning of the assembly does not ensure an ideal hover, but coupled with a light headwind, it can bring a particular help unknown to date on these categories of aircraft.
